Female sex, vegetarian status, nutritional knowledge, sleep quality, and excess weight are associated with intention to lose weight among university students: A cross-sectional study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Intention to lose weight (ILW) is common among university students and may be influenced by sociodemographic, nutritional, behavioral, and anthropometric factors. However, evidence integrating these factors in university populations remains limited. Objective: To analyze sociodemographic, lifestyle, vegetarian status, nutritional knowledge (NK), sleep quality, and body mass index (BMI) factors associated with ILW among university students. Methods: An analytical cross-sectional study was conducted among 301 university students. Sociodemographic variables, sleep quality, physical activity, vegetarian status, NK, and BMI were assessed. Poisson regression with robust variance was used to estimate crude and adjusted prevalence ratios (PR/aPR) and 95% confidence intervals (95% CI). Results: The prevalence of ILW during the previous 12 months was 56.8% (n = 171; 95% CI: 51.1-62.4). Female sex (aPR = 1.29; 95% CI: 1.03-1.61; p = 0.028), vegetarian status (aPR = 1.28; 95% CI: 1.08-1.52; p = 0.004), poor sleep quality according to the PSQI (aPR = 1.22; 95% CI: 1.13-1.32; p < 0.001), and excess weight (aPR = 1.94; 95% CI: 1.55-2.42; p < 0.001) were associated with a higher prevalence of ILW. Compared with high NK, low NK (aPR = 0.62; 95% CI: 0.44-0.87; p = 0.006) and medium NK (aPR = 0.79; 95% CI: 0.63-0.99; p = 0.041) were associated with a lower prevalence of ILW. Conclusion: ILW was frequent among university students and was independently associated with female sex, vegetarian status, higher NK, poor sleep quality, and excess weight. These findings may inform university-based strategies for nutrition education, sleep health, and supervised weight-management counseling.
